Every driver in the United States has probably been stuck in a traffic jam at some time during a commute. No doubt it didn’t come close to a traffic jam on Wednesday in Beijing when thousands got stuck in traffic. The huge traffic jam was caused by a new checkpoint that caused 50 lanes to merge into 20 lanes, according to USA Today on Friday.

You might never again complain about traffic backed up on a three-lane or five-lane highway. It is nothing compared to the traffic jam in Beijing, China where thousands of commuters were trapped on the G4 Beijing-Hong Kong-Macau Expressway, one of the country’s busiest roads. CityLab on MSN reported that some people called the traffic jam a “carpocalypse,” and others called it “carmageddon.” Drivers were returning from celebrating China’s Golden Week when over 750 million people, or half of China’s population returned home after a week-long holiday. Even though the foggy weather contributed to the massive jam, it was due mainly to the newly installed checkpoint that forced vehicles to merge into fewer lanes.

ABC News reported that the jam was so bad that traffic was backed up for hours during the end of one of the busiest tourist events of the year. Millions of tourists made trips around the country to celebrate China’s week-long National Day getaway. It must have been a nightmare for those caught in the traffic jam, but it is an amazing sight to see when looking at the drone footage captured by Chinese news portal Sohu TV that shows just how bad the traffic jam really was.
